如果没有铝件淬火加热的专用设备,而需要进行铝件淬火,可利用现有的中温箱式炉,在炉底板上垫一块比零件大的石棉板,把零件放在石棉板上,再用一个薄铁筒把零件套住(见图),这样可以避免炉底板直按传热和电阻丝辐射。同时把热电偶 If there is no special equipment for quenching and heating aluminum parts, and the need for aluminum quenching, the existing oven can be used in the furnace, the furnace floor pad a piece of asbestos than the parts, the parts on the asbestos board, and then A thin iron tube covers the part (see photo), which prevents direct heat transfer from the furnace floor and resistance wire radiation. At the same time the thermocouple
